Abstract
An image carrier cleaning device includes: a first charging member which charges an image carrier to the same polarity as that of a toner after a transfer operation of a toner image formed by the toner charged to a predetermined polarity and having an external additive added thereto; a cleaning member which comes into contact with the image carrier charged by the first charging member; and a second charging member which applies an electric charge having a polarity opposite to a polarity of the toner to the image carrier having passed through the cleaning member.
